Patent FR-2242051-A1 (FR)
Title: Device for winding hair into curls - spiral spring is pre-loaded to rotate shaft carrying e.g. curler
IPC: A45D1/10
Filed: 1973-08-31
Abstract: Hair curler rotates under spring recoil to effect the winding of a tress of hair onto the roller (14): a shaft (11) bearing the roller housing in a handle piece (12) and the roller and handle being connected by a spiral spring (21). In operation the assembly locks onto teh hair tress, the handle i s rotated against a light hair tension and the spring which is tensioned or compressed. Movement of the appliance towards the hair root then causes the roller to rotate under spring recoil to take up slack hair. The handle can be attached to curling irons (14) or tubular combs fitted for heating and blowing. Pref. the roller or iron incorporates an adaptor haunch (10) which screws into the handle (12).

Title: High frequency welding of composite shoe soles - for rapid assembly of leather PVC rubber components
IPC: B29C65/04
Filed: 1974-01-07
Abstract: Shoe soles, incorporating a core sole made of hide with a coating of pigmented PVC and a wear sole made of abrasion resistant rubber, are assembled by die cutting the component layers to shape and then subjecting them to intense high frequency heating while superimposed to fuse and bond the interface by a state of thermal shock. Offers more rapid and cheaper construction than assembly of hand lasted hide and rubber soles by means of stitching and/or chemical adhesives. Cost saving of about 50% quoted. Facilitates incorporation of non-skid components or surface profiles. The mould tool should be made of matl. of low dielectric loss. Pref. at least one face of the mould carries a relief pattern to be generated on the visible portion of the rubber wear sole; pref. the pattern enhances the grip of the mould tool on the rubber insert.
Patent FR-2261648-A1 (FR)
Title: Static converter with load current monitor and control - increases commutation frequency to handle rapidly-changing loadings
IPC: H02M7/525
Filed: 1974-02-20
Abstract: The static converter has a pair of main thyristors alternately allowing current to pass to the load. A commutating circuit switches the capacitor through to an inductor which turns-off the conducting thyristor. The time between the commutating circuit becoming active and the switching-on of the non-conducting thyristor is equal to a stipulated time interval. The current through the load is measured by a small transformer. A circuit responds to rapid changes in this derived signal from the transformer and produces a control signal that reduces the previously-mentioned given time-interval so that the static converter is effective even with rapidly increasing loadings.

Title: Standardised data communication interface - uses binary standardising signal and data interface
IPC: H04L5/14
Filed: 1974-04-16
Abstract: In association with each processor is an adapter assembly including wired or microprogrammed logic for signal conversion and data exchange procedures. The adaptor assembly has a data interface specifically adapted to that processor concerned, and a communication interface forming an interconnectable junction of invariable arrangement. This junction, for predetermined transmission norms, includes at least one (n+1) path channel for transmission of elementary data of n bits which is representative of a fraction of an information word. An accompanying binary signal signifies in one of its states that the transmitted data is a set of signals, such that the vocabulary of this set which is made as rich as that of other data effectively permits the standardisation of exchange procedures and signals suitable for any processor.

Title: Sprinkler for fire extinguishing system - spring and fusible link operated by pressure or heat
IPC: A62C37/10
Filed: 1974-06-10
Abstract: The sprinkler head (2, 7) is screwed into the system (1). Around the nozzle end (11) of the sprinkler is a spring (4), rated at a predetermined pressure, its other end (12) fixed to a support block (6). A disc (3) blocks the sprinkler nozzle, being held in place by a liquid filled glass ampoule (5, 8), whose pointed end (9) is seated on soft rubber (10) in the support block. At normal temperature, spring pressure keeps the assembly sealed. Heat from a fire will open the sprinkler head by causing either the glass ampoule to break, or a pressure rise in the system to overcome the spring and release the disc.

Title: Rapid connection for a pipe socket - incorporates circular integral sealing ring for vacuum or pressure
Inventor: BOLEAT YVES
IPC: F16L37/06
Filed: 1974-06-18
Abstract: The connection element is for a temporary sealed connection between a vacuum-, high vacuum-, or pressure system, and an element, having a pipe socket. The connection surface has a circular groove, opposite to the socket, to accommodate a solid elastic sealing ring. A channel opens into the base of the groove, to supply a compressed fluid, which lifts the seal off the groove base, and simultaneously presses it against the socket and the groove sides. The seal (16) is integral with a circular cross-section, and a material diameter, smaller than the depth of the groove (17). When at rest, the seal has an internal ring diameter, smaller than the base of the groove, when the socket (1) engages over the cylindrical surface (15); and vice versa, if the surface engages over the socket.

Title: Multicoloured toilet soap mfr - by extruding mixed pieces of different coloured soaps
IPC: C11D13/14
Filed: 1974-07-12
Abstract: Soap shows well-defined zones of different colours which are in the form of veins and give a marbled effect, which is maintained throughout the cake while it is being used. Different batches of soap are prepd., each of a different colour; these are cut into fragments of uniform dimensions and mixed together in fixed proportions of each colour in an extruder, having >=2 cylinders. Pieces of e.g. white, yellow and blue soap are fed into the hopper and a mass of multicoloured soap forms in the first cylinder; this is passed through a circular plate into the second cylinder. It receives a further mixing and a degree of compression in the extension to the cylinder and the mass is extruded in the form of a bar, its section being determined by the shape of the outlet. The multicoloured bar is cut into pieces which are then pressed into the usual toilet cakes. These have a pleasing appearance which is retained until the soap is used up.

Title: Total reflection refractometer with combined collimator - produces separated light and shade image of direction against graduated scale
Inventor: MARQUET ANDRE
IPC: G01N21/43
Filed: 1974-12-10
Abstract: A total reflection refractometer is used to measure refractive indices of substances and particularly that of liquids. Parameters varying in the same manner are also measured. A collimator built into the reference prism block permits a graduated scale and the direction of total reflection to be superimposed. A reference prism (1) is mounted on a handle (7) and pivots on an axis (8) against action of a return spring (10). This action holds the reference face (3) of the prism against a shoulder on the top surface (11) of the handle on which a sample is placed. The scale (14) is mounted in a slot on the prism lighting entry surface (2) forming the collimator with the reflection surface (3). This permits observation of the scale at infinity. A separated image of light and shade against the scale enables the refractive indice to be obtained.

Title: Automatic setting unit for X-ray camera - has capacitor system measuring and setting radiation range and power
IPC: H05G1/38
Filed: 1975-03-12
Abstract: The unit has a TV camera for recording the X-ray image of the patient, the video signal used to obtain information relating to the position of the significant parts of the image in turn used to select the required measuring fields in the trajectory of the X-rays, and the selected fields defining the instant of release and hence the tone of the film. Each measuring field is associated with a capacitor, which stores the mean amplitude of the video signal from the part of the TV image spatially corresponding to the measuring field. A peak value measuring unit for the video signal amplitude storing a value corresponding to the maximum intensity of the Xrays, is used to release the measuring fields corresponding to capacitors with a stored value only slightly below the peak value over a large time interval.
